Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart;
(Colossians 3:22.) Seeking to please masters only so long as their eyes are on them: as Gehazi was very different in his master's presence from what he was in his absence, (2 Kings 5:1-27.) Men-pleasers - not Christ-pleasers (cf. Galatians 1:10; 1 Thessalonians 2:4).
As the servants of Christ - Christ's 'bond-servants' will not make 'men-pleasing' their aim.
Doing the will of God - the unseen but ever-present Master: the best guarantee for serving faithfully your earthly master alike when present and absent.
From the heart - literally, soul (Psalms 111:1; Romans 13:5).
